Yousef Steel is a reliable manufacturer and supplier of ASTM A588 GR.A/B Corten Steel Sheets and Plates based in Riyadh, Saudi Arabia. We pride ourselves on delivering top-notch weathering steel products that are perfect for both structural and architectural uses. ASTM A588 is a high-strength, low-alloy structural steel celebrated for its outstanding resistance to atmospheric corrosion. It forms a protective oxide layer that helps prevent further rusting, which often means you won’t need to paint it for many applications. Our corten sheets and plates are commonly used in bridges, buildings, facades, and various industrial structures. At Yousef Steel, we offer ASTM A588 sheets and plates in a range of grades, dimensions, and specifications to meet global industry standards.
ASTM A588 GR.A/B Corten Steel Sheets and Plates are made with a blend of copper, chromium, nickel, and phosphorus, along with the usual carbon, manganese, and silicon. This unique composition boosts their resistance to atmospheric corrosion and enhances their mechanical strength. They have a minimum tensile strength ranging from 485 to 550 MPa and a yield strength of 345 MPa, showcasing excellent elongation and toughness. The protective rust layer that develops over time adds to their durability in tough environments. These sheets and plates also offer good weldability, formability, and resistance to environmental factors, making them ideal for long-lasting structural and decorative projects.

ASTM A588 GR A/B Corten steel sheets and plates are used on a large scale in construction, bridges, and architectural structures for their high strength and weather-resistance. These are best suitable for use under outdoor conditions like facades, roofing, and railway cars as they form an anti-corrosive rust coat that avoids secondary corrosion. Industrial chimneys, transmission towers, and marine ship transportation also make use of steel plates. Their low maintenance and high durability make them ideal for hostile environments, with long-term performance in structural use.
